EUGENE W. KIING, 0F SYRACUSE, NEW YORK, ASSJIGNOR T0 SEM-ET-SJOLVAY COM-PNY, 03F SOLVAY, NEW YORK, A. GORPOTIO'N 0F NEW Y0 l' il connapplication met necember To all whom it may concer/n:

Be it known that ll, EUGENE W. KING, a citizen of the United States,residing at Syracuse, in the county of @nondaga and State of New York,have invented certain new and usel'ul Improvements in Coke UvenS, ofwhich the following is a specitication. f

My invention relates articularly to that type or class ot ovens own asnon-recovery ovens in which the combustible gasesy generated in theovens are not treated lo-r the recovery ot by-products but are takendirectly to the heating tlues and burned therein to provide heat for thecoking ot the oven charge. Such ovens are employed in the coking oitcoal which is delicient in those elements which it is commercially worthwhile to recover as by-prod-4 ucts.- rlllhe gas generated isconsequently lean in quality and one of the objects ot my .improvementsis to provide for the efficient utilization ofthis gas in heating theoven. To this end my invention consists in providing means tor theconservation of the heat ot the gas as it comes from the o-vens so thatit is delivered to the heating tlues and burned in a hot state and alsoin providing means tor heating the air used to effect the combustion otthe gas Another object of my improvements is to avoid the 'formation inthe heating dues of deposits of the tar,

pitch and other impurities with which the gas coming trom the ovenswithout cooling or scrubbing is charged,

The invention will be` best understood by reference to the accompanyingdrawings, illustrating an embodiment thereof. Fig. l ont which shows avertical cross section ot an oven block, partly broken away to show thecombustion dues, Fig. 2 shows a vertical section longitudinal ot Vtheoven block. Fig?. shows a section on the line 3-3,` Fig. Ll; ig. a showsa section on the line 4 4,- lFig. 3; lllig. 3P is a partial horizontalsection showin the gas connections to the burners; anllig. 5 is asection showing on an enlarged scale details ot due construe? l ltion.

cate a series of coking ovens,

Referring to the drawings, A A, indilorming a block of retort ovens,which are separated by division walls, B, B. Along the top of theblockot ovens, longitudinal thereof, are @El two gas collecting mains,C, C, each of which rires,

ae, taai. serial no. tente.

ranged in two sets each extending half the length of the oven, andseparated by a divii sion wall, l?, and connected by an upper Hue, 4c..I

' Below each oven are located two regenerators, G, l-l, which arerespectively connect ed by ports, q, h, with sole dues, l, il. The soleflues ll. are connected by ports, c', j, with the lowermost combustionlues l, l.

Between the regenerators, G. H. are located tlues, M. N. which runlongitudinally of the oven block and are connected at the end thereofwith a vreversing valve, V, through which, alternately, air is admittedto the regenerators and the gases ot combustion How to the stack. Fromthe gas collecting mains, C, C, narrow passages, K, K, formed in thedivision walls, B, by side passages, L, L, with the gas burner ports,1c, lo, of the combustion iues. ylhe flow ot gas to the gas burner portsis regulated by slide bricks, Z, 4Z, located in the passages, L, whichare readily accessible through ports, 0, in the front and rear walls.

Since the gasfrom the collecting mains may be delicient in heatingquality l have4 provided means consisting of gas supply l), extendingalong the sides of the oven block and 'having branches, p, p, by whichgas from a supplemental supply, as producer gas, can be led `to thecombustion lues. By this means the hot, raw gas from the collectingmains lcan be supplemented ywith other or richer gas, or other gas canbe substituted for the oven gas and the oven gas otherwise disposed'ont.

ln the operation of the oven the gas driven od' from the coal passesfrom the ovens by passages, D, into the gas collecting mains, C, andthence directly downward by passages K, and side passages, L, to theburnerports, lc, where it is met by the air for come bustion. Since thegas passages, K, and sidef B, lead downward and are connected passages,L, are located in the hot division walls between the ovens the gas losespractically no heat but is delivered at the burner ports atsubstantially the same temperature at which it leaves the ovens and thusgives its maximum heating ei'lect.

In case a cold supplemental gas Vis mixed with the oven gas at thecombustion iues the combustion of this is also promoted by the heat ofthe hot oven gas with which it is mixed.

The air for combustion, entering through one of the lines below theoven, as M, passes ,through and is heated in the regenerator, G, andthence passes into the sole flue, I, and by port, z', to the lowermostcombustion Hue l. Thence it passes upward through the several iues tofiue, 4, by which it crosses to the uppermost flue, 3, of the other set.The hot gases of combustion pass out from the lower-most flue by port,j, to sole iue,J, and thence to regenerator, H, and flue, N, by whichthey pass to the stack.

Upon reversal the airflows in the oppo site direction, entering throughthe regenerator, I-I, and the products` of combustion pass out throughthe regenerator G. In either case all the air required for thecombustion of the gas is delivered at one end of the series ofcombustion lues and hence is in excess until it reaches the last of thegas burners. f

- Thus any deposit of tar or pitch formed in the heating lues is burnedout, first from one end of the series of iiues and then from the other,so that any accumulation thereof in the fines is prevented.

In the arrangement shown the gas collecting mains act as pressureequalizers for the gas from the ovens so that gas is supplied to theoven burners at a uniform pressure and also serve to equalize thetemperature of the gas so that there will be no local cooling of thegas, 'as upon charging an oven. In case of excess of pressure in the`collecting mains gas can be bled off tothe air or transported for useelsewhere. Bv manipulationof the slide valves S, S, (Fig. 4) whichcontrol the passages K, I), any lindividual oven can be cut out, as forrepairs, without affecting the operation of those remaining in run.

Having thus described my invention what I- claim as new and desire tosecure by Letters Patent is l. In a block of retort coke ovens,separated one from another by dividing walls, the combination of twosets of horizontally disposed heating iues, connected in series,

on each side of each oven, vertical gas -passages located within thedividing walls and arranged to deliver gas from the ovens directly toone end of the heating fines of each set and regenerators located belowand parallel with each oven and arranged to deliver heated airalternately to thel bottom fines of said sets of heating fiues.

2. In a block of retort coke ovens, separated by dividing walls, thecombination of two gas collecting mains running longitudinally of theblock of ovens and arranged to receive gas from the ovens, two sets ofhorizontally disposed heating iiues, connected in series, on each sideof each oven, gas passages located within the dividing walls andarranged to deliver gas from the collecting mains to one end of theheating iiues of each set and regenerators located below and parallelwith each oven and arranged to deliver heated air alternately to thebottom iiues of said sets of heating lines.

3. In a block of retort coke ovens separated from one another bydividing walls the combinationof two sets of horizontally disposedheating lues, connected in series, on each side of each oven, verticalgas pas sages located within the dividing walls and arranged to delivergas from the ovens to one end of each set of heating flues, means foradding other` gas to or substituting the same for the oven gas andregenerators located below and parallel with each oven and arranged todeliver heated air alternately to the bottom flues of said sets ofheating lines.

4. In a block of retort coke ovens sep* arated one from another bydividing walls the combination of two sets of horizontally disposedheating lues, connected in seriez. on each side of each oven, verticalgas pas sages located within the dividing walls and loo arranged todeliver gas from the ovens to burners at one end of the heating lines oieach set, means for cuttingoff or regulating the supply of gas at eachot' said burners and regenerators located below and parallel 105 witheach oven and arranged to deliver heated air alternately to the bottomfines oi said sets of fines..

5. In a block of retort coke ovens separated by dividing walls thecombination of 110 two gas collectin mains running longitudi* nally ofthe bloc of ovens and arranged to receive gas from the ovens, two setsot heating flues on each sideof each oven, said two sets of filles beingseparated by a dividing 1.15 wall and connected in series by aconnecting, Hue, gas burners at one end of the tlues of each set, gaspassages located within the dividing walls between the ovens andarranged to deliver gas from said gas collecting mains to said burnersand regenerat'ors located below and parallel with each oven and arrangedto deliver heated air alternately to the bottom fines of said sets ofiues.
